Hardcover. Condición: new. Hardcover. High voltage testing of some of the electrical equipments e.g. insulators, cables, transformers as per standard specifications has been explained. Various methods of non-destructive testing which yield information regarding life expectancy and long term stability or otherwise of the insulating materials have been discussed. The book takes a view of various types of transients in power systems and suggests classical and more modern statistical methods of co-ordinating the insulation requirements of the system. Key Features: *Electric Stress Estimation and Control using various techniques. *Mechanism of breakdown of gases, liquids and solid insulating materials. *Application of insulating materials for different electrical equipments. *Generation of high a.c., d.c. and impulse voltages and currents for testing of electrical equipments. *Various techniques and circuits for measurements of high voltages. *Testing procedures for testing of insulators, cables transformers, circuit breakers etc. *High Voltage Schering Bridge and partial discharge measurement techniques for assessing life expectancy of equipments. *Insulation coordination and over-voltage protection.* Photo plates to give a physical feel of various equipment in a high voltage laboratory. *Large number of solved examples, practice problems and multiple choice questions. The book provides a clear, systematic and exhaustive exposition of various discussions of High Voltage Engineering. Generation of a.c., d.c. and impulse voltage for testing of electrical equipments as per standard specifications have been explained.
